SPECFICATION forming part of Letters Patent No. 690,355, dated December 31, 1901.

Application filed June l0, 1901.

T @ZZ whom, it may concern:

Be it known that I, CHARLES N. BROWN, of Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Circular Looms, of which the following is a specification.

This invention relates to a new and useful improvement in circular looms; and it consists in the novel features of construction and relative arrangement of parts hereinafter fully described in the specification, clearly illustrated in the drawings, and particularly pointed ont in theclaims.

Reference is to be had to the accompanying drawings, forming a part of this application, wherein like characters are used to indicate like parts wherever they occur.

Figure 1, in front elevation, shows a machine constructed in accordance with my in vention, showing the cop-ring and cops, ten' sion-ring and thread-guides carried thereby, and the outside rail of the raceway. Fig. 2 is a top plan view of the machine, showing the cop-ring, the tension-ring and threadguides, the raceway, and shuttles therein; also the shuttle-bobbins and the shuttle-supporting track. Fig. 3 is a sectional view on the line 3 3 of Fig. 1 looking in the direction of the arrow.

Fig. 14 is a de- 7o tail View showing a shuttle-roll, a sheddingroll, and a shuttle-point of a succeeding shuttle, the shedding-roll serving to drive the preceding shuttle and form the shed for the succeeding roll. Fig. 15 is a detail View of 75 the clutch-pulley, stop-slide, and clutch-lever. Fig. 16 is a detail view showing the arrangement of the stop-slide and the magnet. Fig. 17is adetailperspective View showing the relative position of the warp-threads with rela- 8o tion to the shedding-wheel. Fig. 18 is a detail view showing the arrangement of the warp and shuttle threads when the latter are being fed into the warp. Fig 19 is a diagrammatic view showing the arrangement of the circuits for operating the automatic stop.

The legs 1 and the general framework of the machine may be of any preferred construcl tion.

2 represents a base-plate having the gen- 9o eral form of a ring, said plate being secured by bolts 3 to the top of the legs 1.

4 represents a cop-ring secured by bolts 5 to the ends of brackets 6, extending outwa rd and upwardfrom the base 2.

7 represents a series of bobbins or cops carried by suitable spindles. (Not shown, as they are concealed by the cops.) The spindles are arranged so that the cop or bobbin stands at an angle to the vertical axis of the Ico f machine, as shown. This construction and arrangement enable me to construct the machine in a compact form, while at the same time the inclination of the cops serves to prevent them from being raised onV the spindle by action of the thread. This inclination of the spindles is further an advantage in placing the cops on the spindles and removing them.

8 represents thread-guides carried by the cop-ring 4. As shown, there is a thread-guide for each pair of cops; but this number may be varied as desired, the warp-thread 7 passing from the cop through the devices hereinafter described, that are carried by the copring and tension-ring to the work.

10 represents vertical brackets extending up from the base-plate 2 inside the cop-ring. (See Fig. 2.) 1l represents the ring secured by bolts (not shown) to the upper ends ofthe brackets 10.

12 represents (see Fig. 10) a ring secured by bolts 13 to the upper side of the ringlll.

14 represents a ring, of insulating material, arranged between the rings 11 and 12. The bolts 13 are insulated from the ring 11 by insulating-washers 15.

From the ring 12 and integral therewith rises a circular hub 16. (See Fig. 10.) This hub is formed with slots 17 at stated interva'ls, there being as many slots 17 as there are cops 7X. This hub 16 is provided with a circular track 17 on its inner wall,formed by rib lSand a shoulder 19. (See Figs. 7and IO.) 2() represents brackets extending outward and upward from the ring 111. (See Fig. 1.) To the outer ends of these brackets is secured atension-ring 21.

22 represents vertical thread-guides near the outer edge of the ring 21.

23 (see Fig. 12) represents a plate secured by screw 26 and the screw-threaded ends 24 of the thread-guides 22 to the top of ring 21.

25 represents a spring secured at its free end to the plate 21 by the thread-guide 22. 26 represents a screw having itshead in engagementwith the top of the plate 25. The end of thisscrew is arranged within a complementa] recess 21 in the plate 21. `By this construction the grip or tension of this springr uponthe thread can be Varied as desired. Thespring 25 near its free end is formed with a thread-eye 27.

28 represents two thread-eyes, one arranged near the free end of spring 25 and the other a short distance inward, but in substantial radial line from the other.

29 represents a take-up, shown as a spring, secured by a screw 30 to the plate 21. At its .free end the take-up is formed with a threadeye 31, arranged normally between the th readey'e 28 and maintained in its normal position by a warp-thread 7'AL against the tension of the take-up. When, however, a warp-thread is broken,y the arm 30 of the take-up dies back and engages the contact-pin 33.

34 represents a wire,ofconducting material, having the lineal shape of a ring and secured l by blocks 34 and screws 33 to the under side of the ring 2l. (See Fig. 12.) The-contactpins 33 at their ends engage the wire 34. The contact-pins 33 are insulated from the ring 21 by washers 35, ot' insulating material.

I have only shown one thread-eye 8 for each pair of cops 7X; but this arrangement may be varied as desired.

The tension-ring 21 carries a tension device with stop attachment for each bobbin or cop or thread, said tension device comprising the said eye 22, spring 25, and the thread-eye 2S, said stop attachment comprising the take-up 29, thread-eye 31, and contact-pin 33. The warp-thread 7n of each cop passes through a thread-eyeS, (see Fig. 1,) then up through the thread-eye 22 and vdown through the threadeye 27 of the spring 25, and then out underneath the lower end of saidspring, (see Figs. 11 and 12,) then through the thread-eye 28 and the thread-eye 31 of the take-up 29 toward the center of the machineto the work, approaching the latter in a tangent.

Referring to Fig. 3, 40 represents arms projecting downward and inward from the ring.2. 4l represents a hollow hub carried by the inner ends of the arms 40. 42 represents a slee ve arranged in the h ub 41 and locked thereto by a set-screw 43. 44 represents a sleeve loosely mounted on the sleeve 42. 45 represents a bevel-gear secured by set-screws 46 to the sleeve 44 and arranged to turn therewith. 47 represents brackets extending outward from the upper ends of the sleeves 44. These brackets at their upper ends are formed with bearings 43. In the drawings there are four of these arms 47; but this nulnber may be varied, as I may use one or more. 49 represents a sleeve arranged upon the sleeve 42 above the sleeve 44. 50 represents a beveled gear arranged upon the sleeve 49. 51 represents set-screws passing through the flange of the gear 5 0, through the sleeve 49, and locking both gear 50 and sleeve 49 to the sleeve 42. 51X represents a series-of radial arms carried by the upper end of thesleeve 49. 52 represents a ring carried by the ends of the arms 51X, said ring constitutingand being hereinafter referred to as a track. 53 represents radial-arms projecting outward from the ring or track 52. These arms at their outer ends support and carry a ring 54, constitutingand being hereinafter termed the inner rail of the raceway 5. K

Referring to Fig. 5, which isasectional view below the plate 2, the legs 1 are shown as formed with ears 56. 57 represents a rectangular framework secured by bolts 5S tothe ears 56. The framework 57 is formed upon each side of the machine with two depending arms 61. In these arms are formed slots 60, in which blocks 59 are arranged to slide and be adj usted back and forth by set-screws 62. These blocks are formed as bearings for shafts 63. 64 represents grooved feedrolls mounted upon shafts 63, there being two of these feed-rolls, having grooved peripheries situated opposite each other, as shown in Figs. 5 and 1, in or- ICO IIO

IZO

der to grip and feed down thewoven material 1701). While I have shown the feed-roll 64-as formed with a grooved periphery, I do not wish to be understood as limiting myself to such congnration, since these rolls willhave their periphery shaped to suit the particular material shaped on the looms. The material after it is formed passes down through the sleeve 42 to the feed-rolls. 66. represents a shaft mounted in the framework 57 at right angles to and over the shafts 63. The shaft 66 is provided with two right-and-left worms, meshing with the worm-gears 68 on the shafts 63, the .parts being arranged to turn the feedrolls 64 in the direction of the arrows in Fig. 1 to draw down the woven material. 70 represents a hanger carried by the hollow hub 4l.V (See Fig. 6.) A complemental outer hanger 71 is carried by the under side of the cop-ring 4. (See Figs. 1 and 6.) 72 represents a shaft mounted in the hangers 70 and 71. 73 represents a frictionwheel slidingly se cured by spline 74 upon the shaft 72. 75 represents a screw-thread arranged in a socket 76, carried by hanger 71. 77 represents a screw-threaded hand-wheel upon the outer end of the rod 75, and the rod 75 may be moved in and out by the engagement of the screw-threads of the wheel 77 with the screwthreads ofthe rod 75. The inner end of the rod carries a roller 7S, arranged in a grooved hub 79, carried by the wheel 73. The rod is formed with a slot 75, in which a pin 75, carried by the socket 76, engages to prevent the rod from turning. 80 represents a sprocket-wheel fast on the shaft 66. 81 represents a sprocket-wheel fast on the shaft 72. S2 represents a sprocket-chain connecting said wheels, the wheel S1 being the drivingwheel and the wheel S0 being the driven wheel. The leg 1 adjacent to wheel 73 is formed with a bearing, in which is arranged a shaft 90.- The inner end of this shaft oarries a bevel-gear 91, that meshes with the gear 45. 'Io the outer end of this shaft 90 is secured a cone or friction pulley 92, arranged with its sloping side in alinement with the ,periphery of the wheel 73, so that said wheel as it is slid in and out to vary the speed may be always in contact with the periphery of the pulley 92. The pulley 92 is preferably made of fiber or some suitable non-slipping material. The leg 1, opposite the leg that carries the shaft 90, is also formed with a bearing, and in this bearing is arranged a shaft 100. (See Figs. 1 and 15.) 101 represents a beveled gear carried by the inner end of the shaft 100 and meshing with the gear 45. The outer end of this shaft carries a loose pulley 102 and a clutch 103. A sleeve 104 (see Figs. 1 and 15) is arranged to slide on the outer end ofthe shaft 100. This sleeve-upon its inner end has a cam or inclined surface 106, arranged between the outer ends of two arms 105, projecting outward from the pulley 103 and connected to the expansion-ring of the clutch-pulley in the ordinary way. 107

represents an arm extending outward from the ring 2. 108 represents a lever pivoted to the arm 107. The free end of this lever is provided with a handle 108, and between the handle and the arm 107 this lever is formed as a ring 109, that embraces the sleeve 104 and is secured thereto by set-screws 110 in the usual way. The sleeve 104 is not affected by the rotation of the shaft, but may be slid in and out by the lever 108. The inward motion of the sleeve 104 serves to set the clutch, while the outward motion serves to unlock or release the clutch, as is usual. 111 represents a spring arranged 011 the shaft 100 (see Fig. 15) between the sleeve 104 and the hub of the clutch 103, the latter being stationary upon the shaft. This spring serves when the lever 10S is released, as hereinafter described, to automatically move the sleeve 104 outward and unlock the clutch. 112 rpresents a slide connected to the inner end of the lever 108. The inner end of this slide is arranged in a casing 114 and is formed with a shoulder 113. (See Fig. 16.) The slide between the lever and the easing may be snpported by a bracket 115 or in any desired way to permit the free movement of the slide. In the casing 114 is arranged an electrical magnet 116, whose armature 117 has its free end formed as a detent 118'.

Referring to Figs. 16 and 19, 116a represents wires comprising the circuit for the magnet 116. 116b represents the battery. One of these wires 116u is connected to the tension-ring 21, thus including the general framework of the machine. The other wire 116 is bifurcated, one branch, 116, being connected to the ring 34, while the other branch, 1l6d,is connected to the hub 16. This ring 34, as stated, is provided with the contact-pins 33 and is supported underneath a stationary ring 21 by means of' blocks 34 and screws 34h, of non-m agnetic material,as hereinbefore stated. 119 represents a lever pivoted to the casing by a pintle 120. This lever at its lower end is formed with a lug 121, adapted for engagement with the detent 118. A spring 122, connected at one end to the casing and at its opposite end to a pin 123 in the lug 121, serves to automatically move the lower end of thelever 119 to the left in Fig. 16. 124 represents a lever carried by a pintle 125 `above the lever 119. The lower end of the lever 124 is arranged to engage a projection 126 in the upper arm of the lever 119. The upper end of the lever 124 is'arranged to engage the shoulder 113 on the slide 112. 127 represents a stop pin or lug against which the upper end of the lever 124 strikes when not in engagement with the shoulder 113 in order to limit the movement of said lever and maintain it always in position for engagement by the shoulder 113. 128 represents a spring connected at one end to the casing and at its other end to the lower arm of the lever 124. The springs 122 and 123 work in harmony and serve not only to keep the com plemental ends IOO IIO

of the levers 119 and 124 in engagement, but also keep the upper end of the lever 124 against the stop-pin 127 except when the upper end of the lever 124 is temporarilypushed to the right by the shoulder 113. The slide 112 has sufficient vertical play to permit the shoulder 113 to ride over the upper end ofthe lever 124 when being moved from its inoperative or dotted-line position to its operative or full-line position. When the. slide 112 is moved inward to set the clutch and start the machine, the lug113 is slid to the fullline position, as shown in Fig. 16, in engagement with the upper end of the lever 124.v The pressure of the spring 111 causes the shoulder 113 to move the lug` 121 back under the lug 118 of thev armature in a position to be engaged by the lug 118. The armature thus holds the clutch set or locked until the circ'uit of the magnet is closed by the arm 32 engaging the contact-pin 33, when the armature 117 is attracted, thus releasing the lever 119. The spring 111 being stronger than springs 128 and 122 throws the shoulder 113 to the right from Fig. 16 against the tension of the springs 128 and 122. After the shoulder 113 has passed to its dotted-line position the springs 122 and 128 snap their. respective levers back to the position as shownin Fig. 16 ready for the next closing motion of the sleeve 106 and with the lug 121 in position underneath and inside of the lug 118 whenever the magnet releases the armature.

Referring to Figs. 2, 4, and 14, 130 represents a shaft carried in the sleeve 48. There are, as shownin Fig. 2, four of these sleeves, each one of which carries a shaft 130. To the inner end of each shaft 130 is secured a beveled gear 131, meshing with the gear 50. (See Fig. 4 and the central part of Fig. 2.) Each shaft upon its outer end carries a shedding-wheel132, these wheels lying in a plane outside of and adjacent to the inner rail 54.l

The engagement is such (see Fig. 4) thatas the gear rotates it carries with it the sleeve 44 and the arms 47, causing the wheels 132 to move in the path of a circle about the rail 54:

By reason of the gears 131 and the stationary gear the Wheels 132 are made to rotate as they travel along the rail. The periphery of each shedding-wheel132 carries shedding-iingers 133. In the particular construction shown each shedding-wheel 132 is provided with eight shedding-ingers, Fig. 14, in which. a half of one of the shedding-wheels is shown. The number, however, of these shedding-fingers may be varied, depending upon the number of warp-threads or the order or arrangement in which it is desired to have the warpthreads lifted, as will be readily understood by those skilled in the art.

Referring to Figs. 2, 8, 10, and 14, 150 represents an angular-shaped frame inside elevation, (see Fig. 8,) that in a top edge plan view (see Fig. 7) has the lineal shape of the arc of a circle. 151 represents a point secured by a piutle 152 to the pointed end of to the rolls 155 156 157.

the frame 150. 153 represents a bolt passing through a slot 154 in the point 151, said slot being carried by the framework 150. By this arrangement the end of the point maybe adjusted up and down. The frame 150 is arranged between the inner rail 54 and the inner surface 54a of the hub 16. The rail 54 and the surface 54a constitute the walls of a raceway in which the frame 150 travels. 154"L represents an arm or piutle on the inside of the frame 150, near its front or pointed end. This piutle-carries a roller 155, arranged to engage the top of the rail 54, (see Fig. 7,) and supports the front end of this framework 150. 156 and 157 represent two rollers carried by said framework 150, near its middle and rear end, respectively, said rollers arranged to rest upon the shoulder 19. (See Figs. 7 to 10.) 158 159 represent two rolls carried by the frameworkv150 and arranged at right angles Rolls 158 159 are arranged to engage the surface of the rail 54 and the surface 54b of the hub 16, traveling between the parts named as a raceway, as shown in Figs. 2 and 7. The rolls 158 159 serve to guide the framework 150 in its circular path, while the rdlls 155 156 157 serve to support and guide the frame 150 in the plane of its movement by engagement with the top of the rail 54 and shoulder 19. (See Figs. 7 to 10.) 160 represents a roll carried by the rear and lower part of the framework 156 and adapted to be engaged by the shed-wheel 132, the shuttle being driven by the shed-wheel through the medium of the roll 160, the roll 160 and the shed-wheel 132 turning in the direction of the arrows in Fig. 14. 161 represents an arm carried by a sleeve 162, arranged upon a shoulder of the sleeve 48 and secured thereto by setscrews 163. This arm at `its free end carries a roll 164, (see Fig. 8,) said roll being arranged beneath, just iu front ofthe roll 160 and on the opposite side thereof from the wheel 132. The roll 164 serves to maintain the roll 160 iu engagement with the wheel 132 and prevent racing of the shuttle and keep the shuttle always in proper relation with the wheel132. 165 (see Fig. 7) represents-a bobbin-frame connected to the frame 150 and projecting inward toward the center of the machine. The frame 150 165 and the parts carried thereby constitute the shuttle. In the drawings four shuttles are shown-one for each shedding-wheel. The number of these shedding-,wheels and shuttles, however, depends upon the product to be woven and the particular arrangement desired of the Warp and the weft threads. My invention includes a machine of the class described where one shuttle or shedding-wheel or more than one is employed. The frame 165 is secured in place by screws or rivets passing through lugs 166, carried by the frame 150. 167 represents a thread-dragging finger carried by the rear end of the framework 150. The inner end of the frame 165 carries an apertured lug 168, adapted to receive the spindle 159 of the bobbin 170.

IOC

IIO

' represents a spindle arranged in said bearing 1741 and having its forward end arranged in the lug 168 of the framework 165. 176 represents a roller carried on the spindle 175 and arranged to turn and run on the track 52 to support (see Fig. 10) thc inner end of the framework 165. 177 represents a plate carried by an extension of the bearing 174. 178 represents a spring secured in a slot in the end of spindle 175. This spring 178 near its free end is formed with a threadguide 179. 180 represents a screw passing down through the spring 178 and the plate 177 and taking into the extension ofthe bearing 174. free end of the plate 177, throughwhich the shuttle-thread passes after passingl beneath the guide 179 on the free end of the spring 178. 10, is just beyond the guide 179, the latter being merely shaped to engage the thread, but not inclose it. By means of the screw 18() the guide 179 may be adjusted toward or from the plate 177 in order to grip the shuttle-thread 170 with any desired tension, these parts in eect constituting a tension. The forward side of the framework 165 is formed with an aperture 182, through which the thread 170a from the bobbin 170 passes; 183 represents a rod arranged at one end in the aperture of a lug 184, carried by the framework 165, adjacent to the aperture 182. (See Fig. 7.) This rod 183 is arranged near its outer end to slide in a lug (not shown) carried by the framework 165. The outer end of the rod 183 is provided with a contact-shoe 185. (See Fig. 7.) 186 represents a spring arranged on the rod 183 between the lug 184 and a pin on the rod 183. 187 represents an aperture in the inner end of the rod 183. The function of the spring 186 is to throw the shoe 185 outward in engagement with the hub 16. (See Figs. 7 to 10.) The thread 170 passes (see Fig. 7) through the aperture 182, through the aperture 187 of the rod 183, thence down through the thread-eye 179 of the spring 170% thence through the thread-eye 181, (see Figs. 7 to 10,) and thence to the work 170". The pull of the thread 170a is suiiicient to keep the shoe 185 out of engagement with the huo 16. Upon the breaking of the thread 170 the spring 186 will throw the shoe'185 against the hub 16. The hub 16 is connected by a wire 116d to one of the wires 116a of the magnet 116, while the shoe 185 is connected to the other Wire of said magnet through the framework of the machine and the ring 21, (see 181 represents 'a thread-eye on the The thread-eye 181, as shown in. Fig.l

Fig. 18,) so that upon the breaking of the shutt-le-thread 170a4 the magnet will be operated to unlock the clutch and stop the machine. 190 represents an insulating member carried by the framework 150 upon its outer side to engage with the rib 18 of the hub 16 (see Fig. l0) .in order to prevent contact being made at that point, due to the lifting of the shuttle or other outward movement ofthe latter. The various parts of the shuttle are further insulated from the hub 16 by means ofthe rollers 156157 158 159, all of which are of nonvconducting material.

Referring to Fig. 4f, it will be observed that the fingers 133 are upon the outer or rather project from the outer side of the wheel 132, leavingthe periphery of said wheel unobstructed for engagement Ywith the shuttlewheel 1GO. (See Figs. 2 and 14.)

Instead of having the point 151 or nose of the shuttle stationary and forming the shed by means of the fingers 133 ofthe shedding-wheel 132 I may dispense with the said lingers 133 and employ the wheel 132 as a shuttle-driver only. In this construction-to wit,where the lingers 133 are dispensed with-I pivot the nose of the shuttle and provide means carried by the shuttle adapted to engage a thread that has passed the nose of the shuttle and tilt said nose to make the latter pass above or below the succeeding thread or threads, as may be desired.

Referring to Fig. 7, it will be noted that the slots 17 in the hub 16 are tangential and extend in a general direction of the motion of the shuttle to prevent binding of the Warpthreads.

In Fig. 11 the ringer 167 is for the purpose of dragging a raised warp-thread into its proper slot 17, there being a tendency on the part of the raised warp-threadto drop crosswise of the inner mouth of its slot 17 or over the corner of the vinside of the rear Walls of its slot 17, the warp-thread always remaining in the outer edge of its slot 17.

Referring to Figs. 1 and 2, the operation of my improved loom is as follows: The handle 108 is pushed inward to set the clutch. This starts the shuttles and their respective and complemental shedding-wheels moving in the raceway between the rail 51 and the hub 16 in a direction opposite the movement of the hands of a watch, (in Fig. 2.) The parts are so arranged and timed that when the flngers 133 on the wheel 132 are employed to form a shed or any of the forms of the pivoted nose of the self-shedding shuttle the nose of the shuttle will pass under and over the'warpthread in a predetermined order, which order IOO IIO

is determined and controlled either by the shedding-wheel or by the pivoted nose of the shuttle, depending upon which construction is employed. A warp-thread 7 from the cop or bobbin 7X (see Figs. 1, 2, and 11) passes through a thread-eye 8, then up through a thread-eye 22, then through a thread-eye 27, and then through the two thread-eyes 28 and v through its proper slot 17 in the hub 16, and

l under tension.

thence across the rail 54 to track 52 to the aperture of the sleeve 42, through which the 'finishing material is drawn by the feed-roll 64. As the shuttle is driven by the wheel 132 around the machine (see Fig. 14) the warpthreads 7a, that are passed under the shuttle, will be dragged between the periphery of the wheel132 and the wheel 160. This actionv puts the take-ups 29 (see Figfll) still farther passes the wheels 132 160, it has some slack, which by the snapping action of the take-up 29 is thrown on top of a nger133, and thereby transported-to the right (in Fig. 14) until it is engaged by and carried upon the top of the nose of the shuttle. Following now the thread that went over a preceding shuttle, when this thread 7b leaves the rear end of the shuttle it is engaged by the nger167 and compelled to reenter its proper slot 17. The parts are so timed that when this thread 7b drops from the finger 167 a finger 133 is beside the roll or Wheel 160, so that as the particular warp-thread 7b falls upon the wheel 132 it strikes upon the periphery of said wheel between two fingers 133, and is thus carried beneath the nose of the shuttle. The parts are so timed that when the thread 7L snaps from under the roll 160 a finger 133 is between that roller and the nose of the succeeding shuttle to receive that thread and place it over the top of the nose of the shuttle. Instead of the threads being handled singly, as described, or alternatively any desired number of the threads of the warp may be handled in any desired sequence, depending upon the timing and arrangement of the iingers 133 or the timing and arrangement of the movement of the nose of the self-threading shuttles, as Will be readily understood by those skilled in the art. The rail 54 is notched, as at 54a, and track 52 at 52a, to receive the warp-th reads to prevent bruising of the latter by the-rolls 176 or 155. If for any reason a particular warp-thread breaks, the arm 32, making contact with the pin 33', will close the circuit, vitalize the magnet 116, and thereby automatically and instantly stop the machine. The shuttle or weft thread 170 is led from the bobbin or cop 170, carried bythe shuttle, (see Figs. 7 to 10,) through the aperture 192, through the aperture 187, through the aperture 178, to the work 170b,where itis placed-above or below the Warp-threads in a jpredetermined manner, controlled either by `the shed-wheel or the pivoted nose of the shuttle, as already described.

Should for any reason the shuttle-thread 170a become broken, the spring 186 will throw the shoe 185 in contact with the hub 16, thereby vitaliz- When the warp-thread 7V ing the magnet 116 to automatically and in- 65 stantly stop the machine.

Manifestly the several details in the machine may be variously modied.

I believe myself to be the first to form a woven fabric by means of a shedding-wheel and shuttle moving in unison or a shuttle having a shedding-nose, and I desire to claim the same in the broadest possible man ner, although in the present application I do not claim specifically a shuttle having a shedding-nose, as the same is claimed by me in another application and only referred to in this application for the sake of completeness, said other application filed December 6, 1901, being serially numbered 84,937.

Having thus explained the nature of my invention and described a way of constructing and using the same, though Without attempting to set forth all the forms in which it may be made or all the modes of its use, what I claim, and desire to secure by Letters Patent, is-

1. In a circular loom, a shuttle, a sheddingwheel, arranged to travel in unison therewith and provided with one or more shedding members arranged to change the plane of a predetermined warp thread or threads with relation to the nose of the shuttle.

2. In a circular loom, a shuttle, a sheddingwheel arranged to travel in unison with the shuttle and provided with two or more sets of shedding members arranged in dierent planes, the nose of the shuttle being arranged between said planes.

3. In acircular loom, two shuttles arranged to move in the path of a circle, a wheel between said shuttles, and arranged to drive the forward shuttle, means upon said wheel arranged to change the plane of predetermined warp-threads with respect to the plane of the nose of the'succeeding shuttle.

4. In a circular loom, a shuttle and a shedding device arranged to move in unison in the path of a circle, and means carried by said device arranged todisplace certain warpthreads to permit the shuttle to lay its thread between said displaced and other warpthreads.

5. In a circular loom, a-shuttle arranged to move in the path of a circle, a shedding device arranged to travel in unison therewith, a stationary hub formed with tangential slots through which the warp-threads pass to the 'shedding device and the work, and means IOO IIO
